The patch ASoC: SOF: Intel: only support INFO_BATCH for legacy platforms has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 4c02a7bd43e22f4de53ad55b94d24e4388f712f0 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Date: Thu, 24 Oct 2019 16:03:18 -0500 Subject: [PATCH] ASoC: SOF: Intel: only support INFO_BATCH for legacy platforms The current position update is not precise enough for PulseAudio to work reliably with the timer-based scheduling on Baytrail, Cherrytrail, Broadwell. Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that the position is only reliable and updated during period_elapsed events. This will be reverted when the firmware provides a more accurate position for those platforms.
